Some of the old ones use a highlift jack to set up, not exactly safe or convenient.

After watching some good enough load outs sell at auction, I ordered a new one from Sioux Steel. Actual one man set up in 5 minutes or less, and only $500 more the what chutes that were 20-30 years old and needed work were bringing. New 16” tires and packed bearings almost made up the difference.
